A switched-mode Class F power amplifier is provided for parallel connection with at least one other like amplifier, within a Chireix architecture, for combining the signals output therefrom. An input component includes at least one active device configured to be alternately switched by a signal input thereto to present an amplified signal corresponding to the input signal and constituting a low output impedance voltage source. A lumped element impedance inverter is provided between the input component and an output resonator component, the impedance inverter being configured for transforming the low output impedance voltage source to instead constitute a high output impedance current source configured for said parallel connection. In accordance with the invention, the negative reactive component values required by the impedance inverter are eliminated and effectively provided by incorporating those values into pre-selected reactive components of the input and output components. Further, a source-drain parasitic capacitance across the active device is eliminated by one or more pre-selected reactive components of the input component, the value(s) of which effectively compensate for the parasitic capacitance.

Aspects of the invention relate to resonator assemblies for use in non-uniform flow environments. The resonator assemblies include one or more features, such as a box or a scoop, for substantially equalizing the pressure on the resonator. In the box configuration, a box is attached on top of the resonator. The box has a top plate with a plurality of openings and at least one side wall extending from the entire periphery of the top plate. A plenum is defined between the box and the resonator plate. In the scoop configuration, a scoop is attached to the top of the resonator such that the scoop substantially overhangs the resonator. The scoop includes at least one side wall extending substantially perpendicularly therefrom, except for one side without a side wall so as to provide an opening into a space defined between the scoop and the resonator.

An air cleaner and resonator assembly is formed from a lower shell portion and an upper shell portion that are joined together to define an interior cavity having an inlet through which air is drawn. An exit tube, formed within the lower shell portion, directs air from the inlet to the engine. A middle shell portion is positioned within the inter cavity and is joined to both the upper and lower shell portions. A lower portion of a resonator is molded into the lower shell portion and an upper portion of the resonator assembly is molded into the middle shell portion. The upper portion is aligned with the lower portion and the middle and lower shell portions are welded together to form a sealed resonator chamber that attenuates engine noise. The upper and lower shell portions are then welded together to form the air cleaner and resonator assembly. Air filters are installed within the interior cavity and are selectively accessible through movable covers installed in the upper shell portion. The air filters are mounted on tube mounts molded into the middle shell portion and rest on cradle mounts formed on the lower shell portion.
